Answer:
I think D
Step-by-step explanation:
Answer:
answer C is the right one
Step-by-step explanation:
Volume cylinder is area of the (round) surface * height.
The formula for the area of any circle = pi * radius²
pi * radius²
So the formula for the volume is
Volume cylinder = pi * radius² * height
radius = 15 in and height = 6 in
Substitute this in the formula and you get:
Volume cylinder = pi * 15² * 6
Volume cylinder = pi * 225 * 6
Volume cylinder = pi * 1350
so answer C is the right one
Answer: The answer would be two because one of the lines would be a parabolic line and parabolic lines only have at the most two solutions
Cone Volume = (PI * radius^2 * height) / 3
3 = (PI * radius^2* x) / 3
radius^2 = 9 / (PI * x)
radius = square root (9 / (PI * x))
Answer:
20*30km = 600km
15*30km = 450km
600km * 450km = 270000 km^2
Step-by-step explanation:
assuming 1cm --- 30km causes that 2cm --- 60km, 3cm --- 90km, 4cm --- 120km etc. Notice that number of km's is 30 times greater than the number of cm's on a map
using this logic, you calculate both real dimensions of Colorado by multiplying 20*30 = 600 km and 15*30 = 450km
Then we use a formula of an area of a rectangle 
assuming 
and get 
which is an actual area of Colorado
